Once you finish the importer setup, click the Finish & Proceed button. Optionally, you can configure the importer to add a timestamp of the last update and replace or append new data in the BigQuery table. However, you can define the table schema manually by switching the option off. The importer will auto-detect the data schema. A new dataset/table will be created if the provided destination is not found. Learn how to get the JSON key file.Įnter the Dataset name and Table name where you want to import the data. In the Destination account, click Connect and upload the Google Cloud JSON key file. In this section, you can connect your BigQuery account for the data import. Once you’re done with the data transformation, click the Proceed button at the top-right corner. Learn more about calculable columns in Coupler. Add Columns – Create a calculable column with data calculated from existing columns.Sort – Arrange the data sorted in an ascending or descending order of a specific column.You can specify multiple conditions with AND & OR operators. Filter – Set conditions to extract specific data from JSON into BigQuery.You can hide the unnecessary columns from here. Columns Management – Choose the columns you want to import from JSON to BigQuery.The importer lets you shape the data in the following ways: You can transform and process the data before importing it to BigQuery. Now, up to 500 rows from the data source will be displayed on the screen. Optionally, you can add other data sources to the connector. Once you’re done configuring the data source, click Transform Data. It lets you transform and process the JSON data before you import it into BigQuery. Once you’re done with the source configuration, click Finish And Proceed.Īlthough optional, data transformation is the most interesting section of this method. Optionally, you can configure the source to extract only specific columns and data from a defined path. ![]() You can also configure the request headers and URL query parameters if the data source requires it. You can refer to the official API docs of the respective app/service for more details. This address can vary according to the data you want to fetch. In the source configuration, you can define the JSON data source.Įnter the JSON URL (often called endpoint URL) from where the importer can retrieve the data. Create a new importer with JSON as the source and BigQuery as the destination. Sign up for a Coupler.io account and log into it. Getting started with Coupler.io is free & straightforward. It also offers advanced features, such as data transformation and stitching, that you can use to process data before loading. It can connect a JSON data source to BigQuery and auto-update data at regular intervals. You can use third-party connectors, such as Coupler.io, to connect JSON to BigQuery dynamically.Ĭoupler.io is a data integration and analytics platform. ![]() These data sources keep changing with time, and thus, you’ll also be required to update the BigQuery dataset with the latest data. Most web apps and services serve data in JSON format. How to dynamically import JSON data to BigQuery We’ll explore each of the above methods to load JSON to BigQuery. This method requires a good understanding of Google APIs and coding expertise to load JSON data to BigQuery. Programmatic Import (Code & Build Your Connector)īuild a custom data connector in programming languages like Python. This has several drawbacks and may not be suitable for loading dynamic datasetsģ. You can manually import JSON as a data source to create a new table. Google BigQuery supports JSON as one of the data sources for creating tables. You can also transform or process the data before importing it to BigQuery. The Coupler.io connector creates a data pipeline to automate data updates at regular intervals. This is the easiest way to import data from JSON to BigQuery dynamically. Coupler.io (Build & Automate Data Pipeline) Here are three main ways to pull JSON data into BigQuery for analysis:ġ. Most apps and services offer an option to export data to JSON format. It is easily readable, lightweight, and language-independent. JavaScript Notation Object (JSON) is a widely used data interchange format. ![]() What is the most efficient way to load JSON data into BigQuery? Methods to load JSON data to BigQuery ![]()
